What's so special about our climbing zucchini

First off, our zucchinis are delicious. They produce a lot and you can harvest from July through October.

You can't grow most zucchini varieties in garden boxes because they need a lot of room to spread out. They'll take over your garden in no time.

Our climbing zucchini grows upward, not outward. You help it out by guiding its long stem along a trellis. So, it doesn't take up as much space and definitely won't take over.

Sowing and growing

Zucchini is a serious summer vegetable: the seeds germinate between 15 and 20°C. The seedlings don't like colder weather.

So, pre-sow your zucchini seeds indoors, and move your plants outdoors when they're strong and the weather is warm enough.

Pick a patch at the back of your garden box under the trellis. Ideally, you plant zucchini in a side patch so its big leaves can flop over the edge.

A zucchini plant needs a lot of nutrients. Give it some extra MM-Plantfood when you plant it, and add some more in mid-July.

Step-by-step sowing and growing instructions are in the Planty Gardening app.

How do you use zucchini?

Zucchini are tastiest when they're 20 - 30 cm long. Cut them off at their thick short stalk. Harvest early so your plant will produce more flowers. (More flowers mean more zucchini.)

Zucchinis are quick and easy to cook. You can boil them briefly, toss them in a stir fry, make a soup, or grill them. Cubed zucchini is great for omelets or pasta sauces. You can even eat small zucchinis raw.

And yes, the flowers are edible too 🙂
